Problems solved by technology

The external gas enters the combustion nozzle and is fully mixed with the flue gas before being sprayed out. Due to the unreasonable design of the flue gas inlet of the current combustion nozzle, the mixing effect of the gas and the flue gas is not good, so it is necessary to improve it and optimization

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and through the examples. The following examples are to explain the present invention and the present invention is not limited to the following examples.

[0017] Example.

[0018] see Figure 1 to Figure 2 .

[0019] This embodiment discloses a burner, which includes a burner mounting seat 1, an outer air duct 2, a No. 1 venturi 3, a No. 2 venturi 4, an inner air duct 5, a central nozzle 8, and a flame stabilization. Disc 9 , Venturi combustion nozzle 10 and outer casing 11 .

[0020] In this embodiment, both the outer air duct 2 and the No. 1 venturi 3 are connected to the burner mounting seat 1 . The No. 1 venturi tube 3 is embedded in the outer air tube 2 and its front end protrudes from the outer air tube 2 in the axial direction. The No. 2 venturi tube 4 is embedded in the No. 1 venturi tube 3 and the two are coaxially arranged. The inner air tube 5 is...

Abstract

The Venturi combustion spray pipe comprises a gas pipe and a mixing pipe, the gas pipe and the mixing pipe are communicated and connected, the mixing pipe is a Venturi mixing pipe, one end of the mixing pipe is a necking end, the other end of the mixing pipe is an inclined face end, and the necking end of the mixing pipe is communicated and connected with the gas pipe. A plurality of gourd-shaped smoke through holes are uniformly formed in the outer wall of the necking end of the mixing pipe along the circumferential direction; the arc radius of a large hole part of each gourd-shaped smoke through hole is 6-10 mm, and the arc radius of a small hole part of each gourd-shaped smoke through hole is 3-6 mm. The burner is provided with the Venturi combustion spray pipe. The structure of the Venturi combustion spray pipe adopts an integrated design, the number of welding points is small, the service life is long, the Venturi principle is maximized by forming the gourd-shaped flue gas through hole, flue gas can rapidly and efficiently enter the mixing pipe to be fully mixed with fuel gas, the mixing effect is good, and low nitrogen and environmental protection are fully achieved.

Description

technical field [0001] The invention relates to the technical field of burners, in particular to a venturi combustion nozzle and a burner. Background technique [0002] The burner usually includes a central nozzle and a combustion nozzle, a plurality of combustion nozzles are arranged, and the plurality of combustion nozzles are uniformly distributed and annularly arranged around the central nozzle. The gas fed into the central nozzle is used as ignition gas, and the ignition gas is input from the rear end of the central nozzle, and then ignited and ejected from its front end. The external gas enters the combustion nozzle and is fully mixed with the flue gas before being ejected. Due to the unreasonable design of the flue gas inlet, the current combustion nozzle has the disadvantage that the mixing effect of the gas and the flue gas is not good. Therefore, it is necessary to improve and optimization. SUMMARY OF THE INVENTION [0003] The purpose of the present invention ...
